The influence on absorption coefficient brought from shape choice with cylindrical or cone-shaped cavity, square or hexagonal profile, from different closure as air or water, from different material properties and structure sizes, are analyzed based on the numerical calculations. Some general characteristics are summarized. It shows that lowest resonance frequency of sound absorbent coefficient is inversely proportional to volume of cavity and sound absorbent coefficient is proportional to perforated percentage.

2通过数值方法研究了吸声结构内腔为圆柱腔和圆锥腔、基材的剖面形状为正四边形和正六边形、不同背衬、基材材料特性、尺寸大小对整体吸声效果的影响，总结了这些情况下非旋转对称吸声结构的声学特性变化规律，得出腔体体积越大，吸声系数最低共振频率越低；穿孔率越大，吸声系数越大的结论。

Dynamic imaging of these fractures has demonstrated significant mobility at the fracture site and emphasized their abundance in the thoracolumbar junction, which is subjected to high stresses.3,4,19,22 Analysis of the serous fluid in the cavity showed a consistency similar to synovial fluid.20,21 Other researchers also reported a serous/serosanguineous fluid consistency similar to plasma.16,30 Biopsies of the cavity lining demonstrated fibrocartilage within a fibrous stroma, representing a pseudosynovium of a nonunion.20,21 Stallenberg et al,32 prompted by the reports of gas in vertebral pseudarthrosis, reported the presence of air in pseudarthroses of various bones in the appendicular skeleton in a rate of 70%, detected with computed tomography-scanning through the site of nonunion.32

这些骨折患者的动态影像显示在在骨折部位有明显的活动度，胸腰段承受高应力尤为明显[3，4，19，22]。对腔内的浆液分析显示类似滑膜液[20，21]，其他研究人员还报告说浆液/血清样的液体与血浆类似[16，30]。椎体内气体现象中假关节的出现促使Stallenberg等[32]对不愈合四肢骨进行CT扫描，发现有70％的有气体存在。

Results (1)Findings characteristics:small vacuole sign,pleural retraction sign and obstructive pneamonia only oppeared in peripheral lung cancer,thin-walled cavity less than 3 cm in diameter should be seen peculiar sign of it,thick-walled inregular cavity could be found in inflammatory pseudotumor and tuberculoma,spiculate protuberance showed mostly in peripheral lung cancer,but appeared in inflammatory lesion too,air bronchogram,pleural tail sign and long spiculation appeared mostly in inflammatory pseudotumor,calcification,pleurae thckening appeared mostly in tuberculoma.

For some consonants, when they are pronounced, the air doesn't pass the mouth as /m/. for others , when it is passing through the oral cavity, the air will receive this or that kind of obstruction. Or it is affricated at a certain point.

一部分辅音发音时，气流不通过口腔，如；另一部分辅音发音时，气流在通过口腔时，受到这样或那样的阻碍，或在口腔中的某个点受到摩擦。

This paper briefly introduces the current development of supercavitating torpedoes in the world,and explains some confusable terms,including cavity,supercavitation, natural supercavitation ,air supercavitation and cavity number.

在简要回顾各国超空泡鱼雷发展概况的基础上，解释了几个易混淆的与空泡有关的新术语(空泡、超空泡、自然超空泡、通气超空泡和空泡数)，分析了超空泡的形成机理和特点，详细阐述超空泡鱼雷在总体结构和性能、动力推进、控制系统和弹道形式等方面的技术特点，概括超空泡鱼雷与普通鱼雷在结构外形、流体动力布局、系统组成和工作特性等方面的不同之处。

The filter includes a cavity formed by metal hull, the inner of the cavity has a PCB double-faced board which fixed at the side wall of the metal hull, between the up and down inner wall there has a certain air height; one side of PCB double-faced board etches cross nodel line transmission line with destined type.

滤波器包括由金属壳形成的一腔体，腔体内设置一PCB双面板，PCB双面板固定在金属壳的侧壁上，与金属壳的上下内壁具有一定空气高度；PCB双面板的一面蚀刻有预定形状的十字节级联传输线。

It shows that the exhaust resistance at the wind blast end reduces obviously, driven by the 800mA/12V small scale draught fan, average exhausting speed reaching above 4m/s, fairly enough to satisfy the air conditioner's demand for new wind volume. Meanwhile, the conic section of the horizontal profile and the linear design of the longitudinal profile of the exhaust end inner cavity and wind shroud for each outlet greatly reduce the flowed out exhaust, effectively lowering the wind blowing feel of the air conditioner user by playing the function of air diffusion.

经过计算和实际测试表明，该装置的送风末端风口阻力明显减小，在800mA/12V小型风机驱动下，出口平均风速可达4m/s以上，足以满足空调对象的新风量要求；同时，横截面采用2次曲线型设计、纵截面采用流线型的送风末端内腔和出口均风罩使气流流出后风速迅速衰减，起到散流器的作用，有效降低了空调对象的吹风感。
